Description Laurent Goubet CLA 2013-07-02 05:17:16 EDT 
EMF Compare makes use of org.osgi.framework.Version.compareTo(Version) in order to check for the API it can use. Calls to this method will fail in java.lang.NoSuchMethodError: org.osgi.framework.Version.compareTo(Lorg/osgi/framework/Version;)I for Helios and prior versions since "compareTo" changed signature from "compareTo(Object)" (Helios, OSGi framework 1.5) to "compareTo(Version)" (Indigo, OSGi framework version 1.6).

We should be using our own comparison routine for the bundle versions in order to avoid this issue.

Best way to tackle this would be to copy/paster Version.compareTo() in our own code, and call that directly.
